Analytical solution for axisymmetric consolidation of unsaturated composite foundation incorporating permeable columns and impermeable columns
نویسندگان
چکیده
Composite foundation is a widely used treatment technology in geotechnical engineering. This study are derived governing equations to axisymmetric consolidation of unsaturated composite (USCF) incorporating permeable columns and impermeable under instantaneous loading, obtained the final solutions excess pore pressures (EPPs) by using mathematical methods such as variable separation, decoupling, finite Hankel transform its inverse transform. The analytical solution free strain conditions more general representative, it can be readily degraded for variety models EPPs conveniently calculated at any point calculation cell. Through degrading proposed special case verify their correctness, comparative results were found well-matched existing literature solutions. effect various parameters on performance USCF was analyzed, where studied include compression modulus columns, radius ratio number columns. show that increasing area replacement rates accelerate reduce settlement, latter effective. Compared reinforced foundations with only single form or column, combination significantly shorten time enhance bearing capacity ground.

This paper presents the laboratory test results of vertical infiltration on two soil columns of finer over coarser soils subject to simulated rainfalls under conditions of no-ponding at the surface and constant head at the bottom. The main objectives were to evaluate the effect of rainfall intensity and duration; and to provide experimental evidence for soil water redistribution and hysteresis....

a study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
